Answer 1

$\huge{\underline{\underline{\tt{QuesTion:}}}}$

The sides of triangke are in the ratio 3:5:7 and its perimeter is 45cm. What are the sides' lengths of the triangle ?

$\huge{\underline{\underline{\tt{AnsWer :}}}}$

Let the constant be y.

Given ratio of the sides of the triangle = 3:5:7

Given perimeter of the triangle = 45cm

==> Perimeter of the triangle = Sum of all the sides

==> 3y + 5y + 7y = 45

==> 15y = 45

==> y = 45/15

==> y = 3

Therefore, the length of the sides :

==> 3y = 3(3) = 9cm

==> 5y = 5(3) = 15cm

==> 7y = 7(3) = 21cm

This is right solution for your question...⬆️

Answer 2

Answer:

$\huge \fbox \red{answer}$

Let the constant be y.

Given ratio of the sides of the triangle = 3:5:7

Given perimeter of the triangle = 45cm

==> Perimeter of the triangle = Sum of all the sides

==> 3y + 5y + 7y = 45

==> 15y = 45

==> y = 45/15

==> y = 3

Therefore, the length of the sides :

==> 3y = 3(3) = 9cm

==> 5y = 5(3) = 15cm

==> 7y = 7(3) = 21cm
